KP8027 coal burning with cable load tester
1. Scope of application: apply to MT 818-2009 flame retardant cable test on flame retardant, flame retardant cable joint.
2. Standard: MT386-1995, MT 818
According to the corresponding requirements of MT386-1995 coal industry standard design and manufacture.
Conforms to the MT 818-2009 coal mines with cable general provisions
3. The combustion housing:
3.1 chassis overall size: L1100 * * H1300mm W525
3.2 combustion box size: W525 L1100 * * H400mm, volume acuity 0.5 m3
3.3 chassis adopts CNC machine processing molding, circular modelling beautiful generous. High-quality SUS304 stainless material, with beautiful, rust corrosion, etc.
3.4 top of the box body has strong convulsions smoke extraction system, the test is completed, will waste gas exhaust to the outside; During the trial, this is a closed system.
3.5 on both sides of box body is apart from the cabinet bottom mouth open a 120 mm 310 mm place, used to pick up sample load.
3.6 enclosure front can be sealed in the testing of toughened glass observation window, convenient for observation test.
4. The combustion burner:
4.1 material of H62 brass burner, fully meet the requirements of MT386-1995.
4.2 standard power: 500 w.
The crater diameter: 4.3 ￠0.90 + / - 0.03 mm, nozzle lamp length: 1.60 + / - 0.05 mm, the height between nozzles and air inlet is 102 mm, flame tube ￠9.5 mm inner diameter.
4.4 torch Angle: 90 ° vertically (longitudinal axis in a vertical plane and vertical direction Angle of 90 °), adjustable, and the air inlet, inner flame of 70 ~ 80 mm, outer flame of 115 ~ 135 mm, is adjustable.
5. Gas: purity more than 95% of the methane (the user should bring along their own)
6. The temperature measuring system:
6.1 K type thermocouple imports, with 1.0 mm diameter stainless steel pipe do coat.
6.2 intelligent PID temperature controller and match the K type thermocouple. The reading of 0 ~ 999.9 ℃.
7. Load current: 10 ~ 3000 a continuously adjustable.
Main fixture: 8.
8.1 test stents: a total of 4 groups, by the high quality 304 stainless steel, supports and burner with observation window plane parallel to the plane for observation.
8.2 equipped with can be measured when the flame burns inside and outer flame rod.
9. Combustion system:
9.1 adopts relay with temperature control cylinder, the combustion process is fully automatic, can burn in time in the specified temperature range. With a comparison with the conventional manual operation, the test results more accurate, the operation more simple.
9.2 the cylinder: 0 ~ 100 mm.
9.3 air filter: 0 ~ 10 kg can be adjusted continuously. High quality filters, the moisture in the air can be completely discharge, can effectively improve the service life of cylinder.
10. Operating characteristics:
Relay control system, the automatic recording time, continuous combustion time.
10.1 combustion timing: when the temperature of the specimen reaches the temperature 204 ℃, the burning torch will automatically move to the surface of specimen under, began to burn. Automatic recording burning time (according to the rules set, such as the burning of 1 min), when setting the time arrives, the burner automatically return to its original position.
Burning the timer range: 0 ~ 99.99 S/m/h.
10.2 the combustion timing: when the combustion time arrival, the timer automatically timing; If within the prescribed time (such as: fire stop for 4 min), the process, if the sample is burning flame, by the operator press the stop button to stop the clock, recording time, such as within the prescribed time limits, is determined through this sample to check.
A burning timer range: 0 ~ 99.99 S/m/h.
11. The ignition method: high voltage electronic ignition, convenient and stable.
12. Working voltage: AC 50 hz, 220 v
